Peter the window is like a dirty filter.;)

I agree. I shoot sometimes inside through glass with my 300mm f4L and still like the image.

Also, even at 600mm, ANY movement sometimes can ruin the sharpness. So if your shooting at 1200mm.... you literally cannot have any possible vibration at all, from my experience. Even the cable wiggling slightly from a cable release could cause some camera shake.

That is a little strange... I'm not criticizing, just asking.
The moon photo attached is unedited except default sharpening in Lightroom (25) with a full frame camera and the Tamron 70-300mm lens (at 300mm) and slightly cropped. By my calculation (if I'm not wrong) your photo is approx a 40% crop. I can't imagine the x2TC makes it so much worse when stopping down and considering the crop, etc. 1/200 should probably be ok too. ISO 400 isn't bad too.
I'm wondering if there was a focus issue, or the 2 second timer wasn't enough, or...?
I would expect it to be better considering my photo.

@ Clarnibass: I do have a Canon 300mm F/4 but was never able to reach the same level of moon-details like yours.
Of course my setup was far from perfect and I suppose even the shake of the mirror moving will lead to this softiness that I have. That and (of course) the cheap TC from Tamron. If weather permit tomorow I'll do the same with my 5dIII (and a bigger crop) for comparison.
For now the grass is greener by the neighbor ;)

Lesson for me is to try to clean the filter/windows.

If it ever warms up.:lol:

Seems like there's no consensus on this lens. Guess I'll have to get one of my own and then decide. ;)

Actually the images posted help him in the decision of keeping the 150-500 Bigmos. I was in the same boat and reached the same conclusion.;)

A 2x TC will make a big difference, but atmospheric conditions can make even more. So you can't compare pictures taken from different locations very reliably.

I can't believe the x2TC makes such a difference that a 40% crop from his setup compares that way with a 90% from my supposedly significantly worse setup. Atmospheric conditions are possibly the reason for this though, thanks.

Maybe atmospehric conditions are the reason, though the photo I posted was taken in my country's biggest and somewhat polluted city and more or less in the center of the city. It's a relatively high city though.

I think atmosphere aside, your setup of APSC and 300mm f/4 lens should be better than my cheap setup of the Tamron 70-300mm lens. At least the farther from the center of the frame (so for the moon it might be more similar). But at 600mm and a x2TC it's a little strange. So I guess we just can't really know because of the different conditions, but that's why I'm wondering if your focus might have been a little off, or vibration from the camera caused blur, etc.

Maybe you can try again sometime, even without the x2TC and use a longer timer and several photos with refocusing to try to be sure...?

Well this morning I did the same with the 5dIII but besides a (tiny) improvement of IQ the result was pretty much the same (even without the TC).
It's clear I'll have to work on my technique - boosting the ISO for speed - trying a larger F-number - using a heavyer stand - ... .
Thanks clarnibass for the help!
